In a way, this can be true. Like men, it would depend on the women who are looking for sex. There are some women who do not need to have sex even if they have to forego sex for years, they are completely fine with this. Of course, there are also some women who feel that they would need to have sex often for different reasons. There are some who may want to have revenge towards other men.
There are some women who just crave sex and they do not care anymore who they are going to have sex with. Women are not biologically wired to crave sex as much as men do but for those who get addicted to pleasure, they just might be desperate for sex.
This is not a sensible question to ask for you can't lump the entire population of women together and guess at their appetite for sex. The range of eagerness (what you call desperate) for sex will be huge, from no interest to extreme interest.
To my knowledge there is no research showing the number of women falling at the upper end of this range, and any such attempt to measure the extent of eagerness for sex would be suspect, for it is a subject where people are unlikely to be at all frank. Men may be more 'desperate' because of their biological make-up, but this is perhaps exaggerated because it's a subject that males feel they must discuss, truthfully or otherwise.
